Cytochrom bd oxidase
WebNADH Cytochrome c Reductase. NADH cytochrome c reductase (E. C. 1. 6. 2. 1.) (Jeng et al. 1968) was determined by follow-ing the reduction of cytochrome c at Er,,™nm at 25'C. The millimolar extinction coeffi-cient utilized for cytochrome c in the cyto-chrome oxidase assay was utilized for this assay. The assay system contained: 33 mM
